With only a handful of 11-inch laptops still available, serious travelers are flocking to ultrathin 13-inch models instead. But the low price and good battery life of the Sony Vaio E keep it from being counted out.

Sony's first ultrabook, the Vaio T, doesn't fall far from the tree of other thin Sony laptops like the Vaio Z, but it's far more affordable: this is ultrabook-as-budget-laptop, not ultrabook as high-end computer.

Samsung's Series 7 Chronos 700Z5A-S03 is the closest Windows equivalent to a MacBook Pro in terms of specs, power, and design and even nearly matches on battery life, but it's $500 less expensive than an entry-level Apple 15-incher.
